Speaking of destroying the furniture, a couple of years ago I bought 2 black chairs joined by a console for our loungeroom as the old chairs were falling apart. The new ones looked new but were secondhand from the Salvos. I got a good deal.
Well I tell you what, they didn't look new for long. The cats destroyed them, scratching them to bits. Kira still lays into them from time to time. They look really ugly now, torn to shreds.
Kira tried it on with my new computer chair as well. I had to put a box on it so he doesn't do any more damage to it.
